概括

动脉静脉 (AVF) 中的术后血流 (Qa) 与血栓形成风险有关. 在远端AVF (dAVF) 中的Lower Qa显著增加了血栓形成,但在近端AVF或AV移植中没有.

科学领域:

血管外科血管外科
腎臟病學 (nephrology) 是一種醫學專業.
医疗器械医疗器械

背景情况:

动脉静脉 (AV) 血液透析通道容易发生血栓形成,这是一个主要的并发症.
目前的指导方针缺乏关于常规监测AV接入血流 (Qa) 的证据.
这项研究调查了在各种AV接入类型中术后Qa和血栓形成风险之间的关系.

研究的目的:

分析术后Qa与血栓形成风险之间的关联.
为了比较这种关联在远端自主AV管 (dAVF),近端自主AV管 (pAVF) 和AV移植 (AVGs) 中.

主要方法:

对191名患者进行了218次AV访问的回顾性队列研究 (2013-2022年).
包括在30天内进行术后QA测量的访问.
卡普兰-梅尔生存分析和多变量考克斯模型评估了Qa和血栓形成风险,具有非线性自然线条.

主要成果:

在1.35年的中位数随访期间发生了66例血栓形成事件.
在dAVF中发现了Qa与血栓形成风险之间的显著非线性关联.
对于dAVF,血栓形成风险在Qa<800mL/min时呈指数级增加,每100mL/min下降到1,289mL/min时,风险增加43%. 对于pAVF或AVG没有发现任何关联.

结论:

手术后的 Qa 是血栓形成风险的非线性预测因子,特别是在 dAVF 中.
测量术后的Qa可能有助于识别高风险的dAVF,以便进行更密切的监测或干预.
这一发现可以改善AV访问监控策略.

关键词:

Hemodialysis I: Introduction

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Venous Thrombosis I: Introduction

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
